I'd suggest that you avoid the Sora component group, at least major components. You will find smoother shifting and better all around performance from the Tiagra group. Plus, Tiagra are easier to upgrade (say, to 105's) than Sora.

I personally don't have a problem with aluminum. Sure, purists will tell you that steel is real etc. but aluminum is lighter. Also, steel frames are generally only available on really cheap or really expensive bikes since it appeals to a select market. Steel is often recommended for dedicated touring bikes, but even that is changing. Carbon fibre is nice, but more than you are looking to spend.

I have a friend who works at a bike shop, and her advice is to haggle on the price. Mention that you belong to a cycling club and find out if they have a discount. Pretty much anyone who asks for a discount will get one. Margins on full bikes are slim, but substantial on accessories. If you get any accessories (bike lights, helmets, locks, racks, panniers, shoes, different pedals, ...) see how much you can get off the price.

I was looking at road bikes last summer, and there are some good prices and deals to be had for for the under-$1000 range.

Once you make your decision, be sure to ride it daily!
